Seam Grip+SIL™ Silicone Seam Sealer

    • Only seam sealer that adheres to silicone-impregnated fabrics
    • Formulated for Silnylon
    • Ideal for ultralight tents, tarps, packs, and garments
    • Unaffected by extreme heat or cold
    • Enough for one backpacking tent/tarp


    Seam sealer seals the holes formed by the sewing machine needle as it stitched the fabric. Left unsealed, rain works its way through those holes and will begin to drip on you in the middle of the night. Who wants to sleep in a puddle? Once properly sealed, you can rest easy.

    Seam sealer also repairs pinhole rips in fabric. Simply applying a small amount over the hole will seal it from leaking.

    Seam Grip+SIL™ Silicone Seam Sealer (formerly SilNet) is specially formulated for Silnylon. It’s the only seam sealer that adheres to silicone-impregnated or silicone-coated fabrics. Only silicone sticks to silicone. Seam Grip+SIL will not bond properly to non-siliconized fabrics (use Seam Grip+WP). Extreme heat or cold will not affect the performance of Seam Grip. Washing is OK.

    One tube seals an average 2-person backpacking tent/tarp. Don’t wait to the night before a trip to seal your tent/tarp. While it takes some time, carefully applying Seam Grip to a new tent/tarp is a right of passage. Take pride knowing that your effort will ensure a dry night when it pours.
